CAR-COUPLING.

SPECIFICATION yforming part of Letters Patent No. 363,783, dated May 24, 1887.

Application filed November 20,1886. Serial No. 219.431.

, therein; and my invention consists in so. eonstructing the parts that the link will not be permanently displaced when the coupling is used in connection with another ear provided 3o jaw J and link L.

with a similar coupling, so that when the cars are uncoupled again my link :requires no manipulation to make it ready to couple with another car; and, further, in confining the operative parts to a space wholly within the drawhead at the part where it is desirable that there should be no projection, and in simplifying the construction of the parts.

In the drawings, Figure 1 is a vertical section of a draw-head embodying my invention. Fig. 2 is an elevation of a similar draw-head. Fig. 3 is a vertical section of the two drawheads. Fi-g. 4 is a vertical section of Fig. 2, the link and hooked jaw being removed. Fig. 5 is ahorizontal sectionof Fig. 2. Figs. 6 and 7 are details of construction. Y

D and D are draw-heads containing hooked In connecting the parts link L is inserted into the draw-head from the front, and jaw J is introduced from the bottom of the draw-head through slot s to the positins shown in Fig. l, when the bar or pivotpin p is driven through hole O in the drawhead and hole o in the jaw J. The rear end of the link is so formed, as shown, that it will catch over and beyond the pin p, so as to prevent its removal from the draw-head, as well as the removal of the jaw J, except by withdrawing the pin.

g g are projections or guides on the inside of the draw-head, whose function is to limit theside-play of the jaw J.

b b are blocks or stops, one on each side of the draw-head, to prevent the link from being driven back into the draw-head in coupling with another car having a similar drawhead and coupling. The front face of these blocks b Z is beveled, as shown, so that if the (No model.)

link accidentally receives a hard blow it will be driven back, sliding up over said beveled face into the body of the draw-head, asindicated in broken lines in Fig. l, to prevent injury to the link; but these blocks will afford sufficient resistance 'to Y prevent backward movement of the link when ititself couples with the opposite car.

In operation whichever link is undermost as the cars come together will, in passing into the opposite draw-headLdepress the jaw J of that draw-head, as indicated in broken lines in Fig. 3, until it gets by the hook of the jaw, when the latter will return to place by gravity. Slipping off the hook ofthe jaw after coupling is prevented by the presence of the idle-link between the hookof the jaw and the top of the draw-head.

The front of the draw-head has the beveled surfacef to guide the operative link into the drawvhead if it should strikebelow the jaw.

To uncouple the cars, the hook of the jaw J is depressed by raising lits rear end by means of chain O. The front end or hook of the jaw J is prevented from rising too higliin the drawhead by projection a.

Throughout the drawings corresponding parts of the two couplings shown are marked with similar letters and primes.

I claim-e 1. In a draw-head, a link and hooked jaw permanently mounted therein, said link norinally projecting from said draw-head, arranged as described, whereby the entering link of the car to be coupled therewith will slide under said link, depressing said hooked jaw until it has passed into place beyond the hook of said jaw, substantially as described.

2. A draw-head having a hooked jaw and link permanently mounted therein, provided with ya stop or stops having an inclined face to hold the link in place when coupling, but
